Please read the whole chapter, I'm not quite diligent to quote a pdf, what I could remember, If they found driver to be unhurt, they should report it to race control to enable them make further decision. It wasn't solely marshal authorities to decide such action, Intervention is made by marshal at that scene unless the clerk of the course made instruction otherwise.
Seems we have to refer to more subsidiaries of chapter to produce more appropriate decision. :D
